Found some bits and pieces while I was tidying up, don't know if this helps you at all. The square bit is a blanking plug for the plate, and it's the same size as the end of the junction box. I can't measure how long that is because I'd have to unwrap my handlebars. It looks as though the hole in your frame isn't wide enough.
